REVERSIBLE CAR-SEAT.

SJPEGIFIGATION forming part of Letters Patent No. 515,937, dated March 6, 1894.

Application filed October 18,1893.

To all whom it may concern-.-

Be it known that 1, JOHN LEMMAN, a citizen of the United States, residing at Wakefield, in the county of hliddlesex and State of Massachusetts, have invented certain new and useful Improvements in Reversible Car- Seats; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention is an improvement in reversible car seats and consists in the novel fea tures of construction and combination of parts, hereinafter fully described, with reference to the accompanying drawings which illustrate the best form in which I have contemplated embodying my invention, and said invention is fully disclosed in the following description and claims.

Referring to the said drawings, Figure 1 is a side elevation of the irons for one end of a car seat constructed according to my invention. Fig. 2 is a view similar to Fig. i show ing the parts in different relative positions.

I have illustrated the irons for one end of a car seat embodying my invention, it being understood that the irons for the other end. are simply duplicates of those shown, and that the back irons and seat irons will be connectedby the back and seat portions of the car seat respectively.

I have illustrated in dotted lines in the figures different positions which the parts assume in reversing the car seat.

Referring to the drawings A represents the end frame of the car seat having the arm portion a and brackets a a, for the reception of the striker arm.

B is the striker arm pivoted at b to the frame A adjacent to the level of the seat portion of the car seat, and extending upwardly at an angle and engaging one of the brackets a.

C is the back iron, to which the back of the car seat is secured, and this back iron 0 is pivoted at or near its upper end to the striker arm, as indicated at c. r The seat iron D to which the seat portion of the car seat is socured is shown in dotted lines to avoid confusion, and is of ordinary construction. The seat iron D is provided ad acent to its cen- Serial No. 488,521. ('No model-J ter with a vertically disposed slot cl which is engaged by a ing b on the lower end of the striker arm, which extends below the point of pivoting b. The end frame A is provided at each side with a curved way or guide A which supports the seat irons and the seat portion and said ways or guides are given such form as will cause the seat to assume a downwardly inclined position toward the back in both positions of the back, the seat portion being moved from one position to the other by. the engagement of the lug b of the striker arm, with the slotted seat iron D.

E represents the locking arm for the back iron, which arm is pivoted preferably upon the pivot b of the striker arm, and is provided with a slot e extending from a point adjacent to said pivot 19 to the outer end of the arm E where said slot diverges and has two branches 6' e as shown in the drawings. The branch slots 6 c I term locking slots and the lower end of the back iron 0 is provided with a lug or projection c which engages one of the locking slots e in the locking arm when the back is in eitherof its operative positions. Each of the locking slots is so formed thatits outer end provides a locking construction so that when the back is in operative position the lower end of the back cannot be forced toward the pivot b, and the parts are preferably so constructed that the pin or ing a of the back will be substantially in a horizontal line with the pivot b.

Both sides of the car seat are exactly alike except that in actual practice it is customary to dispense with the frame A at one side and secure the irons to the side of the car as is well known. I

' The operation of my improved car seat is as follows: When it is desired to reverse the.

car seat, the parts being in the position shown in full lines in Fig. 1, the back is seized by the lower edge, at any point, and raised bodily until the striker arms strike the brackets ct on the other side of the main frame, as indicated in dotted lines in Fig. 1. The back can be seized at any point between the side of the car and the aisle, as the slotted looking arms lock the back in relation to the striker arms. As soon as the parts assume the positions shown in dotted lines in Fig. 1, the jar occasioned by the striker arms forcibly engaging gthe'bireokets a, will cause the his gravity--will cause the lugs c to enter the loeking slots'of the locking arms,when the:

latter will fali, and securely lock The back in l l 7 position. ltwill th'usbe seen that the opeli @a tionofr 'eversiug myimprovedear seatis' exceedingly: simple an d: 1 the: construction is such that itmis assistedglargelybygreivity,

' thus making a very effioient eariseat.
